With the development of science and technology, human beings have mastered many kinds of materials, among which plastic has become one of the most frequently used materials because of its portable, durable, easy to process, low cost and many other advantages. Since plastic was invented, its application has covered almost all industries and fields, such as household, machinery, electronics, chemicals, vehicles and so on.

So, what exactly is plastic? Simply put, plastic is a polymer compound polymerized by long-chain molecules, because the polymerization methods and material sources of different polymer compounds are different, their composition, properties and characteristics are also different. In terms of application, plastics can be made into a variety of shapes and sizes, and additives can be used to achieve better mechanical properties, heat resistance, fire resistance and other properties.

In the market, plastics can be divided into many types according to their raw materials, properties, processes and other factors. Here we will briefly introduce several common types of plastics:

polyethylene (PE): It is a kind of Translucent, with good tear resistance and cold resistance materials, usually used to make feeding pipes, woven bags and other items.

polyvinyl chloride (PVC): It is a white material with good insulation and corrosion resistance. It is widely used, such as water pipes, floors, and wire coatings.

polystyrene (PS): is a kind of foamed benzene board, light, easy to process, used in thermal insulation, tableware, plates, etc.

polyester (PET): is a transparent, hard, tough material, usually used to make beverage bottles, cosmetic bottles, food packaging bags and so on.

above is only part of the common plastic types, each plastic has its own characteristics and application range.

Although plastics are very convenient in our lives, excessive use of plastics can also cause serious environmental problems. For example, plastic bags are difficult to degrade, causing serious environmental pollution, marine garbage and so on. Therefore, we should try our best to avoid the use of plastics in our daily life, reduce the generation of garbage, and use green and environmentally friendly alternatives to protect the environment.

sum up, although plastics are widely used, but its types are different, different plastics are suitable for different fields and occasions, we should choose according to the needs. At the same time, we also need to pay attention to reduce the use of plastic, so as to reduce its impact on the environment, promote environmental awareness.
